The relative importance of the silica particles themselves and the microorganisms that they carry in these health effects remains unclear.
The reddened patches are being scrutinized for their composition of so-called phytoliths, hard little silica particles found in plants, including wood products.
Upon exposure, the trimethylsilane compound bonds to the silica particles while forming water.
Caustic is also added to 'scour' the inside of the boiler tubes and remove any silica particles.
The silica particles provide a high strength material when flocculation occurs.
The size of the silica particles influences inversions, conversions and other properties of the ceramic body.
The Stöber process allows the formation of monodisperse silica particles.
Microporous silica particles can be obtained through organic templating followed by calcination.
By chemically grafting the ligands onto the silica particles, this effect is counteracted.
Small silica particle can potentially cause silicosis when inhaled.
